LTC1647-1CS8#PBF

Hot Swap Controllers Overview

The LTC1647-1CS8#PBF is a dual hot-swap controller manufactured by Analog Devices Inc., designed for safe insertion and removal of circuit boards in live systems. It operates within a supply voltage range of 2.7 V to 16.5 V, featuring programmable current limiting and two independent channels. The device supports soft-start functionality to manage inrush currents during power-up. It is housed in an 8-lead SOIC package and is rated for operation between -40°C and +85°C, with a quiescent current of 1 mA.

Hot Swap Controllers Feature Summary

• Dual-channel architecture for independent control of two hot-swap paths
• Programmable current limit protection against overcurrent conditions
• Integrated soft-start mechanism to regulate turn-on slew rates

Hot Swap Controllers Applications

• Server and storage backplane board insertion management
• Industrial control system module protection
• Telecommunications equipment hot-plug interface circuits

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required temperature grade and package variant. Request official datasheets and test reports to validate performance specifications against design requirements before integration into production systems.

Hot Swap Controllers Selection Notes

Select this component when dual-channel hot-swap protection is required for voltages up to 16.5 V. Ensure the SOIC-8 package fits the PCB layout constraints. Verify that the programmable current limit settings align with the load specifications and that the operating temperature range meets the environmental demands of the target application.

Hot Swap Controllers Part Context

This part belongs to the LTC1647 family of hot-swap controllers, which provides comprehensive protection for high-speed data bus applications. The CS8 suffix indicates the commercial temperature grade and SOIC-8 package configuration. The #PBF designation confirms lead-free compliance and RoHS adherence, distinguishing it from non-compliant variants.
